Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, proudly presents our premium Tungsten Mesh for Vacuum Furnace Heating Elements, designed to withstand extreme temperatures up to 2000°C with exceptional durability. Our tungsten mesh is engineered for high-performance vacuum furnace applications, ensuring consistent heat distribution and long service life. With over two decades of expertise in wire mesh production and annual export value exceeding US$5 million, we deliver reliable solutions to global markets including North America, Europe, and Asia.
Our tungsten mesh is manufactured from high-purity tungsten wire, processed through advanced weaving techniques to achieve precise mesh openings and uniform structure. The material's excellent thermal stability and resistance to oxidation in vacuum environments make it ideal for heating elements in sintering, brazing, and heat treatment furnaces. Below we detail the key features and specifications that set our product apart.
Key Features & Benefits
- Ultra-High Temperature Resistance: Operates continuously at 2000°C without deformation, ensuring stable heating performance.
- Excellent Durability: Tungsten's high melting point (3422°C) and low vapor pressure minimize material loss under vacuum, extending element life.
- Uniform Heat Distribution: Woven mesh structure provides even heat emission, reducing hot spots and improving furnace efficiency.
- Customizable Specifications: Available in various wire diameters (0.05mm–0.5mm) and mesh counts (10–100 mesh) to meet specific heating requirements.
- Low Thermal Expansion: Tungsten's low coefficient of thermal expansion maintains dimensional stability during thermal cycling, preventing cracking.
- Easy Installation: Supplied in rolls or cut-to-size sheets, with optional edge reinforcement for mechanical support.
- Environmentally Friendly: Tungsten is non-toxic and recyclable, aligning with sustainable manufacturing practices.

Applications
Our tungsten mesh is widely used in the following industries:
- Vacuum Furnace Heating Elements: Ideal for high-temperature sintering, brazing, and annealing furnaces.
- Heat Shields & Insulation: Acts as a reflective barrier in vacuum chambers to reduce heat loss.
- Electron Beam Evaporation Sources: Provides stable heating for thin-film deposition processes.
- Chemical Vapor Deposition (CVD) Reactors: Used as heating elements for semiconductor manufacturing.
- High-Temperature Filters: Suitable for filtering molten metals or corrosive gases in extreme environments.
Quality Assurance
Every batch of our tungsten mesh undergoes rigorous testing to ensure consistent quality:
- Material Analysis: Spectroscopic verification of tungsten purity (≥99.95%).
- Dimensional Check: Measurement of wire diameter, mesh count, and width using precision instruments.
- High-Temperature Test: Sample heated to 2000°C in vacuum to confirm structural integrity.
- Visual Inspection: 100% inspection for surface defects, oxidation, or contamination.

Frequently Asked Questions (FAQ)
1. What is the maximum temperature your tungsten mesh can withstand?
Our tungsten mesh is designed to operate continuously at 2000°C in a vacuum or inert atmosphere. For short-term exposure, it can tolerate slightly higher temperatures, but we recommend staying within the rated limit for optimal life.
2. Can I use this mesh in an oxidizing atmosphere?
Tungsten oxidizes rapidly above 400°C in air. Therefore, this product is intended for vacuum or inert gas environments only. If you require oxidation resistance, we can discuss tungsten alloy options (e.g., W-Re) upon request.
3. What are the available mesh sizes and wire diameters?
We offer a wide range: mesh count from 10 to 100 per inch, and wire diameter from 0.05mm to 0.5mm. Custom specifications are available – please provide your requirements.
4. How is the mesh packaged for international shipping?
Our standard packaging includes a strong wooden case with inner moisture-proof material. The mesh is rolled on a core and protected with foam. This ensures safe transit even for long-distance shipments.
5. Do you provide samples for testing?
Yes, we can provide small samples (e.g., 200mm x 200mm) for evaluation. The sample cost is reasonable, and we will deduct it from the bulk order. Please contact us for details.
6. What is the typical lead time for a standard order?
For standard specifications, lead time is 15–20 working days after order confirmation. Custom orders may take 20–25 working days. We can expedite for urgent projects at an additional charge.
7. Can you cut the mesh to specific shapes?
Yes, we can cut the mesh to any shape – circular, rectangular, or custom profile – with clean edges. We also offer edge welding or folding for mounting purposes.
8. How do I ensure the mesh fits my furnace heating element design?
We recommend providing your furnace dimensions, voltage, and power requirements. Our engineering team can help calculate the optimal mesh resistance and layout. Contact us for technical support.
